Couldn't you have the dealer change them out, when your new car arrives?

It looks as if that is what is going to happen,I am just afraid of some of these hacks that they call service techs will do a sh$tty job.I was a service tech at one point in my life and took pride in my work.

I can hear it now(sir that is not a factory exhaust so you cant fault us that it is banging against your undercarriage or that your muffler fell off).
